Building
upon knowledge and skills gained in preceding
grades,
by the end of Grade 4, students will:
Standard 5.7
(Physics)
All students will gain an understanding of
natural laws as they apply to motion, forces,
and energy transformations.
Standard 5.7.3.A
Motion
and Forces
Standard 5.7.3.A.1
Recognize
that changes in the speed or direction of a moving
object are caused by force and that the greater
the force, the greater the change in motion will
be.
Standard 5.7.3.A.2
Recognize
that some forces can act at a distance.
· gravity
· magnetism
· static electricity
Standard 5.7.3.B
Energy
Transformations
Standard 5.7.3.B.1
Identify
sources of heat and demonstrate that heat can
be transferred from one object to another.
Standard 5.7.3.B.2
Identify
sources of light and demonstrate that light
can be reflected from some surfaces and pass
through others.
Standard 5.7.3.B.3
Use
devices that show electricity producing heat,
light, sound, and magnetic effects.
Standard 5.7.3.B.4
Show
that differences in sound (loud or soft, high
or low) can be produced by varying the way
objects vibrate.
